Waiting for WP Xbox Music App update!!

My Xbox music app is crashing. It does not go beyond the green loading screen. And I'm unable to update the app too. Keeps showing the error 8007027 when installing the update every single time. Anyone here knows how to contact support for wp8.1 or any possible fix?

Technically speaking, a week has 7 days, which divided by 2 (early week and late week) would be 3.5 days. Lets say that we take one day for the middle week day, so we still have 3 early days, 1 middle day and 3 late days. It's Tuesday right now. Consequently, they have until tomorrow to deliver the update. And... yes I'm so tired of waiting that did all those calculus in order to excuse Microsoft ******* delay.!
